Extending cables & Cable orientation

For most cables the connector is directly fixed to the back, however in
some applications where space is limited, it may be useful to angle the
cable from the connector in a particular direction.

What appears
obvious to one person is often less obvious to another. As such
orientation definitions vary across interface standards.
Many different connector types are used in machine vision applications
and many of these are available with connectors rotated at specific
angles to enable use in locations with little space. Depending on the
position that the connectors
are viewed from, the terms left, right, up
and down may not always provide enough information to accurately
determine the required orientation.

To ensure customers always receive
the correct cable, independently of the
camera and interface used, we have
defined a naming convention for the
orientation of our cables. As the
mechanical assembly of the interface
connector in regard to the sensor
position might vary among camera
models (often with CameraLink)
it is
firstly necessary to define an independent
reference position.

Definition of camera orientation

The camera has to be aligned so that
the sensor is in the correct horizontal

Definition for circular connectors

For circular connectors (Hirose or other suppliers), the pin arrangement
specified by the manufacturer will apply with the mechanical arrangement
of the connector with orientation pin 1 = UP as reference. After
alignment of the camera in the above described horizontal position, the
desired outgoing direction is defined according to pin 1 of the circular
connector. The drawing shows some examples of commonly used
Hirose connectors with different outgoing directions with view to the camera connector.

Definition for rectangular connectors

For rectangular connectors (like MDR26 - CameraLink, USB and
IEEE 1394) looking at the cable connector end is the reference, viewing
the individual connector pins. The connector has to be positioned with
pin 1 at the top left (male connector) or right (female connector), as
shown in the drawing and the possible directions of the cable output
are marked as R (for RIGHT), L (for LEFT), U (for UP) and D (for DOWN).
